The head and jaws of sarcosuchus resemble those of a modern gharial.

This gargantuan predator is colloquially called SuperCroc, which gives you an idea of what it looked like. Not technically a crocodile, the sarcosuchus was actually its distant relative, the primary difference being their size.

At almost 40 feet long, sarcosuchus was almost twice as long as the saltwater croc, the biggest crocodile we have today. It also weighed around eight metric tons, which meant that it could take on almost any challenger it faced. And that’s a good thing, because sarcosuchus lived alongside the dinosaurs (who often became its lunch).

Check out the sarcosuchus in action:
